大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝支架(jia)(jia):搭(da)設腳手(shou)架(jia)(jia)根據波(bo)紋管的(de)直徑提前(qian)確定，采(cai)用管扣連接鋼管的(de)方式搭(da)設腳手(shou)架(jia)(jia)，形式分A型和(he)B型腳手(shou)架(jia)(jia)長度(du)一般(ban)長25m、克0、6m、高為2d3(d為波(bo)紋管直徑)，B型腳手(shou)架(jia)(jia)一般(ban)克為25m高依據波(bo)紋管直徑大(da)小拼裝接縫位置確定尺(chi)寸。腳手(shou)架(jia)(jia)按上述尺(chi)寸搭(da)設便于施工、

2、拼裝(zhuang)類型與(yu)搭接方式：拼裝(zhuang)以中心軸(zhou)線為基準，由中心向(xiang)兩端(duan)對稱進行安裝(zhuang)，直(zhi)至兩端(duan)。1斷(duan)面(奇數斷(duan)面)、Ⅱ斷(duan)面(偶數斷(duan)面)、加(jia)強斷(duan)面(偶數斷(duan)管(guan)管(guan)片）

3、波(bo)紋管拼裝(zhuang)(zhuang)：采用刻槽法(fa)施工(gong)的地基，安(an)裝(zhuang)(zhuang)吊(diao)車依(yi)據刻槽深(shen)度，依(yi)次安(an)裝(zhuang)(zhuang)底部管片(pian)(pian)。底部管片(pian)(pian)安(an)裝(zhuang)(zhuang)完成后對剩余(yu)管片(pian)(pian)進行(xing)安(an)裝(zhuang)(zhuang)。管片(pian)(pian)安(an)裝(zhuang)(zhuang)同平(ping)基上(shang)的鋼波(bo)紋管施工(gong)。

首圈(quan)波(bo)紋(wen)管(guan)(guan)(guan)圈(quan)為奇數斷(duan)面，拼裝時應(ying)將(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)(yu)地上(shang)(shang)(shang)安(an)裝，使(shi)用(yong)鐵(tie)鉤的(de)(de)一端勾(gou)住(zhu)I斷(duan)面片(pian)(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)(luo)絲囗，用(yong)12噸的(de)(de)吊車勾(gou)住(zhu)鐵(tie)鉤的(de)(de)另(ling)一端，將(jiang)波(bo)紋(wen)管(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)(yu)墊(dian)層上(shang)(shang)(shang)，然后(hou)(hou)使(shi)用(yong)同(tong)樣(yang)的(de)(de)辦法(fa)將(jiang)第二(er)片(pian)(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)按圖3、21斷(duan)面所示的(de)(de)搭(da)接(jie)方式放置，使(shi)用(yong)撬棍將(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)螺(luo)(luo)(luo)栓(shuan)口(kou)對齊(qi)，將(jiang)提前準備好的(de)(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)部涂上(shang)(shang)(shang)渢滑劑，由內冋外插入孔位(wei)；波(bo)紋(wen)管(guan)(guan)(guan)外側套上(shang)(shang)(shang)凹墊(dian)圈(quan)或凸墊(dian)圈(quan)，遇波(bo)使(shi)用(yong)凸墊(dian)圈(quan)，遇波(bo)峰使(shi)用(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外側旋(xuan)上(shang)(shang)(shang)螺(luo)(luo)(luo)母，在用(yong)套筒扳手(shou)預緊(jin)(jin)螺(luo)(luo)(luo)母，然后(hou)(hou)使(shi)用(yong)電(dian)動(dong)扳手(shou)緊(jin)(jin)固螺(luo)(luo)(luo)母兩塊板片(pian)(pian)(pian)洤全部安(an)裝完畢;波(bo)紋(wen)管(guan)(guan)(guan)的(de)(de)螺(luo)(luo)(luo)栓(shuan)安(an)裝完畢后(hou)(hou)，需采用(yong)專用(yong)注膠槍(qiang)于(yu)(yu)端部接(jie)合(he)處、緊(jin)(jin)回件連接(jie)的(de)(de)螺(luo)(luo)(luo)栓(shuan)孔空隙處涂抹中性硅酮耐候(hou)膠。緊(jin)(jin)接(jie)著按2#管(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)施(shi)工拼裝順序，拼裝好首圈(quan)波(bo)紋(wen)管(guan)(guan)(guan)圖36偶數、奇數斷(duan)面交替拼裝順序

4、加強斷面拼裝

當波紋管涵直(zhi)徑較大、填土高度較高時，必須(xu)設置加(jia)(jia)強管片(pian)，稱為加(jia)(jia)強圈”，加(jia)(jia)強斷(duan)面的管片(pian)安裝(zhuang)工序。
